A
Step-by-step explanation:
Answer:
I believe y = 90°
Step-by-step explanation:
70 + 110 = 180, so you know that both sides are the same angle. The angle of the two straight lines must be 90°
I’m not sure but you could probably look it up to see what it is
Answer: 12663.3 cubic inches sand is needed for this sandbox.
Step-by-step explanation:
Formula : Volume of cuboid = Base area x height
Volume of sandbox = 1146 x 13 = 14898 cubic inches
Quantity of sand required to fill = 85% of Volume of sandbox
= 0.85 x 14898 [85% = 0.85 ]
= 12663.3 cubic inches
Hence, 12663.3 cubic inches sand is needed for this sandbox.
Answer:
k = 2a = 10
Step-by-step explanation:
If
x² / 25 − y² / 56 = 1
we know that
a² = 25 ⇒ a = 5
b² = 256 ⇒ b = √256
The equation of the hyperbola defined by |FP − PG| = k can be written as follows:
|FP − PG| = 2*a
then
2*a = 2*5 = 10
